Abstract
The MoS2/MoO3 nano-heterojunction photocatalyst was synthesized via the in situ oxidation sintering method. The properties of the samples were characterized by XRD, SEM, EDX, TEM, UV-vis, PL, FT-IR, BET and electrochemical techniques. The MoS2/MoO3 nano-heterojunction (MS-400) exhibited significantly better photocatalytic activity toward Rhodamine B degradation (0.42634 h-1) than monomer MoS2 (∼8.0-folds) and MoO3 (∼25.6-folds). This is mainly attributed to the MoS2/MoO3 heterojunction interface having an appropriate potential gradient that can promote the interface carrier transportation/separation to optimize the carrier efficiency and increase the solar absorption and specific surface areas/active sites via microstructures.
